摘要
利用2008年5月12日汶川地震余震的P波和S波到时数据,对龙门山地区波速比进行了计算。结果表明,该地区的强余震全部发生在波速比相对较高的地区,这应该是地下介质的破碎原因造成的。
By using the P wave and S wave arrival time data of the aftershocks of the May 12, 2008 Wenehuan earthquake, velocity ratio of the Longmenshan area is calculated. The result indicates that all the strong aftershocks in the area occurred in the region where the wave velocity ration is relatively high, which should be caused by broken underground medium.
